LUBRICATQR.

SPECIFICATION forming part of Letters Patent No. 381,586, dated April 24, 1888.

Application filed February 15, 1888. Serial No. 264,102. (No model.) Patented in Belgium March 31,1885, Xo. 68,201; in England April D, 1885, No. 4,5163 in AustriaeHnngary July 18, 1885, No. 12,042 and No. 37,935, and in France July 3l, 1885, No.'167,6i`5.

To aZZ whom. it may concern:

Be it known that I, MAX'SCIINEIDER, residing at Doos, near Nuremberg, in the Kingdom of Bavaria, Germany, have invented a new 'and useful Improvement in' Lubricators, of which the following isa speciiica'tion, reference being had therein to the accompanying drawings,

(no patents being obtained by me anywhere for this invention, save in France, No. 167,675, dated July 31, 1885; Belgium, No. 68,201, dated March 31, 1885; Austria-Hungary, No. 12,042 and No. 37,935, dated July 18, 1885;

Great Britain,`No. 4,263, dated April 9, 1885.)V4 The object of my invention is to provide a.

lubricator with a screw-actuated `compressing cap or vessel, whereby the lubricating-grease may be forced from the discharge-opening of the lnbricator, and to provide means for so etfectually packing said screw compression cap or vessel to the body of the lubricator that leakage of the grease is prevented and all danger of the'screw-cap working loose on the body disk l, the stem k depending from the center` thereof, and the screw-threaded extension a v on the lower end of the stein, adapted to engage a threaded openingin the bearing or other part of a machine (not shown) to Abe lubricated, so as to secure the lubricator firmly to said bearing or part. The stem k is hollow, and the bore thereof communicates at the lower end with a bore or discharge-opening@ in the extension a. Y Y l o represents an inclined opening whiclr'extends from the upper end of the bore at one side thereof to the upper face of the disk or plate 2, and in thecenter of said sk or plate is a screw-threadedA opening. whi communicates withtheupper end of the bore of the stem. 4MIn the periphery of thepplate or disk is' made a groove or channel, as shown in Fig. 1,inwhich is placed a packing-cord, d, the said cord bei ng wound around the plate or disk andhaving its ends secured firmly in a radial opening, e, by means-of a pin or key, c', as

. shown in Fig. 3.

i g represents an inverted cap or cup which y formsthe cover for the lubricator and the resiervoir for the lubricating-grease.

of the said cap or cup lit 'around the disk or The sides plate l and tightly compress the packing-cord, so that the latter effects a perfectly-tightjoint between the cup or cap and the disk or plate,

and also exerts so much frictional resistance to the rotation of the cup or cap that the latter is prevented from working loose and becoming displaced by the jarring of the machine to which `the lubricator is applied. From the center of thc top of the cap or cup and rigid with or formed integral with the same depends a screwstem, c, which engages the threaded central opening in the disk or plate, and is thereby adapted to raise or lower the cup on the disk when the former is turned,

vas will be readily understood.

The lubricator'being filled with greasel and the cup being`turned, so as tocause it to be forced downward by the screw, the grease is forced through the opening o, the b oreof the stein k, and the opening t' onto the bearing or part of the machine to, which the lubriator is applied and thereby lubricates the same.

In Fig. 2 I show a modifiedform ofmy invention, in which the periphery of the plate Z is plain and is extended downward to lform a depending flange, l', and in which van annnlar groove or recess is made in the inner side of the depending portion ofthe cup and receives and retains a packingfring, b. In this form-of my .invention I also 'provide the cup with radial projecting wings f near its upper side, by means of which the said cup may be more conveniently grasped and rotated, so as 'to force out the lubricant.

In Fig. 4.11 illustrate another modified form of my invention, which is adapted to be usedon crank stuffing-boxes of enginesand other moving parts of machinery which are in constant mption, and thereby render it very hazardous and almost impossible to grasp and operate the cup of the' lubricator; In this form IOO of lny invention the periphery of the plateZ 1s provided with a groove or channel that receives and retains the packing-ring d', and I make the screw-stern c of the cup hollow, so as to communicate at its lower end with the 'bore of the stern k and fit a piston, P', in the bore of said screw-.stem c. The operating rod P of said piston is hollow and is filled to any desired extent with weights sufficient to cause the piston to exert the required downward pressure. The operation of this form of my invention is as follows: Zhen the cup is screwed'downward, the lubricatinggrease is forced into and fills the bore of the stem k, and is also forced up in the bore of screwstem aand caused to raise the weighted piston. As the grease becomes gradually consu medvby the friction ofthe parts of the machine as it is applied thereto through the opening i, the weighted piston descends slowly by its-own gravity on the lubricating-grease in the hollow stems c and k, and consequently forces the y`grease continuously through the opening i as fast as it is consumed. By weighting the piston to' the necessary extent, according to the density and condition of the grease and the amount thereof consumed by the machine or engine in a given time, thelubricator may be so adjusted as to cause the grease to be fed to the machine automatically as fast as the lubricant is needed.

Having thus described my invention, I

cl ai msarees ing the screw-stem c, engaging a. threaded opening in the plate, for the purpose set forth.

3. The combination of the body A, having *the circular plate Z, the depending hollow stern k, and opening o, with the cup or receptacle g, fitting sriugly on the plate A, and having the hollow screw-stem c, engaging a threaded opening in the plate and communicating with theV bore of the hollow stem, and the weighted piston arranged in, the bore of the screw-stem c, all arranged and adapted to operate substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses. f

MAX SCHNEIDER.
